I've actually made lists like that in my head a while ago, but I didnt know where to post them. To be exact I have: Top 20 best Sega Sonic characters, Top 10 worst Sega characters, Top 10 best Archie Sonic heroes, Top 10 best Archie Sonic villains, Top 5 worst Archie Sonic characters, and Top 5 best SU arcs.
The thing is that Top 10 best archie heroes/villans only covers characters like Rotor or Finitevus not like Eggman or Silver,
So,Top SU arcs
5 Forged in Fire (#50) - Epic battle, with some great visuals, pure and simple. Great thing about it is that Metal finally get recognition he deserved. He comes off and dangerous and cunning adversary rather than reccuring glorified mook. My only complain is the ending. Metal blowing up. Again.
4 Scrambled (#37-40) - Part one already sold me with gathering of all grandmasters at one place, all wchich quavered in fear before Doctor like scolded children, all while Cubot and Orbot serve tea. Equally badass and hilarious, which is propably best way to sum up entire arc. Peppers artwork works great: his Snively's seems more ugly and pathetic that usual which really suits him. And every Eggman's expression is just plain hilarious when its not threatning. He even looks egg shaped! Each issue make you love doc more and more untill ending remind everybody that he a complete monster. Also: all scenes with Omega are priceless.
3 Mobius: 30 Years Later (#5-8) Penders 25 Years later was propably dullest story in archie sonic history. 13 issues of bad sitcom and then ending that didnt end anything. It was imposible to like. And then miracle come. Flynn made Lara-Su one of my favourite characters, and made me wish for more stories in future. It made me care for literally every character from King Sonic to Rutan. Good sense of humor, adorable way of writing children and married couples, and actual action: this issue had everything that original Penders work lacked. And it has Mysty-Re, random echidna named by fans, but Flynn declared her name to be canon, thats preety cool too. Not to mention it actually feels like arc, something that could be collected in hard cover more that any other arc,maybe except...
2 The Silver Saga (#25-28) When I think "epic" I think about this one. For start, artwork is gorgeus. Then there is Dark Enerjak, the baddest and coolest vilain in the comic. I cant even describe him, cause in his own words "he's someting to be experienced". Epic feel and sense of danger dont leave for a second. This comic removes all my fears that Flynn haters might be right.
1 Treasure Team Tango (#21-24) So seeing how Silver Saga is the baddest thing ever it seems to be impossible to write something better. And Flynn did it. By writing a goofy story. Cons: Rouge doesnt care about safety of Sol Zone. Pros: everything else. Yardley does perfect job drawing many characters at once, often with humoristic poses and faces (which is especially important for Bark since he cant speak). At the same time Flynn does perfect job of writing many characters at the same time. Its the closest to Blaze or Amy arc we've got and its quite satysfying. Even Team Dark fit into story despite being stereotypically serious characters.. Another cool thing is that characters never become a faceless punching each other crowd. They still think and know when to work together, when to run or when to drop explosives at their opponents. And ending is Bean the Dynamite at his finest.

Thanks, its just me or is Penders a main source of obscure characters for this topic? Sooner or later we'll do all guardians..
Hos about this: I was respected warrior, but one duel changed it all. I was exiled, and I had to join supervillain that made me stronger.

Lightning who? No, I not Lightning! Never even met a guy.

She first appeared in games. Than in anime. Than in comics based on anime. Than Archie Sonic Off-panel. That Archie Sonic back-up story. That Sonic Universe. And finally in main story of Archie Sonic. Who is she?
